Tape cartridge

Abstract

A tape cartridge which can be positioned near a print head is provided. A tape cartridge is loaded in a tape printing device including a print head, a head support frame causing the print head to swivel, and a protrusion provided on the head support frame, and has a print tape. The tape cartridge includes a platen roller which receives a pressing force of the print head; a cartridge case having a platen support section which supports the platen roller; and a receiving section which is provided on the side of the print head, of the platen support section, and receives the protrusion.

The invention claimed is: 
     
       1. A tape cartridge which is loaded in a tape printing device including a print head for printing on a print tape of the tape cartridge, a head moving section holding the print head and moving the print head between a printing position where printing is performed on the print tape and a retreat position retreating from the printing position, and a protrusion provided on the head moving section, and which has the print tape, the tape cartridge comprising:
 a platen which receives a pressing force of the print head with the print tape provided in-between, at the printing position; 
 a cartridge case having a platen support section which supports the platen; and 
 a receiving section which is provided on the print head side of the platen support section, receives the protrusion when the print head moves to the printing position, and has a section to be pressed which is pressed by the protrusion in a loading direction in which the tape cartridge is loaded in the tape printing device. 
 
     
     
       2. The tape cartridge according to  claim 1 , wherein, with respect to the protrusion with which the receiving section is engaged in a moving direction of the print head as an engaging/disengaging direction, the receiving section extends in the engaging/disengaging direction. 
     
     
       3. The tape cartridge according to  claim 1 , wherein the receiving section has a section to be pressed which extends in the engaging/disengaging direction and which is positioned in a direction intersecting with the engaging/disengaging direction by the protrusion. 
     
     
       4. The tape cartridge according to  claim 3 , wherein the section to be pressed includes a slope ascending in an engaging direction of the engaging/disengaging direction. 
     
     
       5. The tape cartridge according to  claim 1 , wherein the section to be pressed of the receiving section is situated below the platen. 
     
     
       6. The tape cartridge according to  claim 1 , wherein the platen is made up of a platen roller. 
     
     
       7. The tape cartridge according to  claim 6 , wherein the platen support section rotatably supports the platen roller. 
     
     
       8. The tape cartridge according to  claim 7 , wherein the receiving section includes an engagement groove formed in the platen support section. 
     
     
       9. The tape cartridge according to  claim 8 , wherein the platen support section has a bearing hole which rotatably supports the platen roller, and
 a distal side of the engagement groove communicates with the bearing hole. 
 
     
     
       10. The tape cartridge according to  claim 6 , wherein at least a part of the receiving section exists within a range of a diameter of the platen roller, as viewed from an axial direction of the platen roller. 
     
     
       11. The tape cartridge according to  claim 7 , wherein the platen support section has a bearing hole which rotatably supports the platen roller, and
 the bearing hole is cut out on the print head side thereof.
